$\log (25) + \frac{\log (8) \cdot \log (16)}{\log (64)}$

Step 1

Rewrite $\log (25)$ as $\log (5^{2})$ .

$\log (5^{2}) + \frac{\log (8) \cdot \log (16)}{\log (64)}$

Step 2

Expand $\log (5^{2})$ by moving $2$ outside the logarithm.

$2 \log (5) + \frac{\log (8) \cdot \log (16)}{\log (64)}$

Step 3

Rewrite $\log (8)$ as $\log (2^{3})$ .

$2 \log (5) + \frac{\log (2^{3}) \cdot \log (16)}{\log (64)}$

Step 4

Expand $\log (2^{3})$ by moving $3$ outside the logarithm.

$2 \log (5) + \frac{3 \log (2) \cdot \log (16)}{\log (64)}$

Step 5

Rewrite $\log (16)$ as $\log (2^{4})$ .

$2 \log (5) + \frac{3 \log (2) \cdot \log (2^{4})}{\log (64)}$

Step 6

Expand $\log (2^{4})$ by moving $4$ outside the logarithm.

$2 \log (5) + \frac{3 \log (2) \cdot (4 \log (2))}{\log (64)}$

Step 7

Rewrite $\log (64)$ as $\log (2^{6})$ .

$2 \log (5) + \frac{3 \log (2) \cdot (4 \log (2))}{\log (2^{6})}$

Step 8

Expand $\log (2^{6})$ by moving $6$ outside the logarithm.

$2 \log (5) + \frac{3 \log (2) \cdot (4 \log (2))}{6 \log (2)}$
